Several studies have defined the staphylinid family as one of the most important in soil ecosystems due to the great variety of roles it plays, including its contribution to decomposition rates in forest plantations. In order to know the composition of staphylinids involved in the decomposition process of necromasses, samples were collected during one year in forest plantations of the Centro de Enseñanza e Investigación Forestal (CIEFOR), Maynas province, Loreto region. The plantations were Ormosia coccinea “huayruro”, Cedrelinga cateniformis “tornillo” and secondary terra firme forest as a control group. Three 50 x 25 m plots were delimited in each plantation. The plastic mesh method with a 5 mm opening was used as a collection method, elaborating 360 bags which were distributed equally in the three plots of each plantation previously filled with their own necromass (leaf litter, branches, flowers, etc.). The extraction and identification of the samples was according to different periods of necromass decomposition. Twelve staphylinid genera distributed in 17 tribes and grouped in 14 subfamilies were identified. The most abundant genera were Trinodromus and Biocrypta. The highest richness and abundance was in the secondary forest, but there were no significant differences with the other plantations. Considering the decomposition periods, richness was significantly higher in the 45-day period, while abundance did not show significant differences.
